The levels of expression were quantified using the QuPath software. PD-1 was detected in lymphatic follicles in affected and unaffected tissue samples and in inflammatory infiltration in IBD. There was no difference between groups neither in PD-1 overall expression nor in individual compartments, with the exception of the mucosal expression. It was higher in the mucosa of CD patients comparing to controls, however this difference was marginal (p = 0.0461). PD-L1 was expressed in endothelium and mesenteric nervous plexi, consistently in each group. There were no significant differences in PD-L1 immunoreactivity in context of histologic compartment nor clinical diagnosis.

Positive regulatory domain member 10 (tristanin) is a poorly studied member of PRDM protein family. Gene fusion transcripts containing PRDM10 were recently identified in low-grade undifferentiated pleomorphic sarcomas (UPS), and associated with pleomorphic morphology and low mitotic index. The aim of this study was to investigate the immunohistochemical staining of PRDM10 in a larger sample of soft tissue sarcomas. Therefore, the study included 118 soft tissue sarcomas from different classes, and PRDM10 antibody was applied to all of them. Immuno-histochemically, staining was observed in 22 (19%) cases, while 96 (81%) showed no staining. When PRDM10 expression was compared with clinico-pathological features, there was a statistically significant correlation between PRDM10 expression and myxoid changes, multi-nucleated giant cells, and surgical margin (p = 0.017, p = 0.034, p = 0.032, respectively). No statistically significant association was found between PRDM10 expression and other parameters. Based on the obtained data, it can be said that PRDM10-positive-stained tumors (tumors with PDRM10 expression) are mostly myxoid, containing multi-nucleated giant cells, and can be removed with well-circumscribed margins.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10652765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study is the first in the English literature to define EMT features in micro-invasive and early invasive oral squamous cell carcinoma (OSCC) under a light microscope. This is a retrospective study of histological sections of 43 cases of OSCC from the Department of Oral Pathology and Microbiology. The data collected were later statistically analyzed. A total of 11 micro-invasive and 32 early invasive OSCC cases were assessed for core features of EMT. The predominant feature defining EMT found was dense inflammatory infiltrate in both microinvasive (91%) and early invasive OSCC (88%) followed by cell individualization in 82% of microinvasive and 75% of early invasive OSCC, which was then followed by other features. Reporting EMT in histopathological reports on a daily basis can aid in early diagnosis of OSCC as well as understanding carcinogenesis in early stages. Thereby, inclusion of EMT targeting therapeutics in early stages of OSCC can significantly alter the prognosis of cancer.","PeriodicalId":49692,"journal":{"name":"Polish Journal of Pathology","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10665896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
